Not a help-gcc but...

I would like to put a request in for two new gcc features.

a)	A primitive that returns the address of the caller to a function (the
	callee).  I could have made use of such a beast for internal program
	debugging numerous times.  I have little to no understanding if this is
	possible/portable/maintainable or not.

b)	I think a vote should be taken on an extension to cpp to handle
	variable argument macros.  Sound goofy?  It is :-).

	#define vmacro (...)		(void)printf(...)
	/* '...' will absorb as many arguments as possible and regurgite them
	   to the '...' in the destination code, comma seperated. */

	Example:
		main() { vmacro("hello %s\n", "world"); }

	would become:
		main() { (void)printf("hello %s\n", "world"); }

	I should have patches for this in an hour or three, if anyone cares.

thanks,
